Embodiment Construction

[0024] An embodiment of the present invention provides a beam allocation method, which is used to improve the reliability and transmission efficiency of a communication system. Embodiments of the present invention also provide related devices, which will be described respectively below.

[0025] The method and device provided by the embodiment of the present invention are applicable to a large-scale multi-cell wireless communication system. For the basic structure, please refer to figure 1. Wherein, each cell includes a base station, and the antenna array on the side of the base station consists of a large number of antennas. Unlike the present stage where each base station is configured with only 8 antennas, the number of antennas in each base station in the embodiment of the present invention may be hundreds or thousands. The cell where the base station is located can be divided into multiple sectors, and users in sectors with the same number can multiplex the same time-fr...

Abstract

The invention provides a beam allocation method, being used for improving the reliability and transmission efficiency of a communication system. The beam allocation method comprises the steps of receiving a detection signal sent from a first user on a first beam; determining first long-term channel information from the first user to the first beam according to the detection signal; acquiring second long-term channel information in a second base station; and allocating the first beam according to the first long-term channel information and the second long-term channel information. An embodiment of the invention also provides a related apparatus.

Description

technical field [0001] The present invention relates to the communication field, in particular to a beam allocation method and related base stations. Background technique [0002] Multiple-Input Multiple-Output (MIMO, Multiple-Input Multiple-Output) technology is one of the basic technologies of modern communication. By setting multiple transmitting antennas and receiving antennas at the transmitting end and the receiving end respectively, the signals are transmitted and received through multiple antennas at the transmitting end and the receiving end, which can improve spectrum utilization and power efficiency, thereby improving communication quality. [0003] Space division multiplexing is a communication technology based on MIMO. This technology transmits as many independent data as possible on the spatial channel through different antennas, so as to make full use of the multipath component in the spatial propagation, so that the channel capacity increases with the The in...
